As digital broadcasting services have been rapidly deployed, many service operators are considering more effective transmission of digital broadcasting services. Recently, the digital broadcasting services have been changed to use resources efficiently and transmit them to easily accommodate the varying needs and environments of subscribers. Therefore, it is necessary to redefine the IP-based Digital Video Convergence Service (DVCS) for maintaining QoS (Quality of Service) and using bandwidth effectively for transmission on broadband network environment. The IP-based DVCS is a service system for distributing digital video via IP-based broadband networks. It is the service system for providing interfaces and functionalities to enable the service operators to offer quality of service-guaranteed broadcasting to subscribers via IP-based converged broadband networks. This Recommendation defines the specification of IP-based DVCS considering the convergence environment. It defines the specification of IP-based DVCS including IP-based Switched Digital Video (SDV) technologies considering the convergence environment. It is based on ITU-T J.1111 ” Requirements for the advanced IP-based digital video convergence service” and J.1112 “ Functional Requirements for IP-based digital video convergence service.
